Apron Flashing - AF

Tamlyn AF7 Apron Flashing — Reliable Wall-to-Roof and Chimney Leak Protection

The Tamlyn AF7 Apron Flashing is a purpose-built metal flashing component designed for efficient wall-to-roof and chimney-to-roof connections. It is manufactured in a 90° profile and available in Builder (Bldr), Standard (STD), or 26-gauge Galvanized (26 Ga GZD) material, as well as standard painted colors. This product is suited for contractors, roofers, and builders who need a dependable, code-compatible flashing solution that prevents water infiltration at critical transition points in the building envelope.

What sets the AF7 apart from generic flashing components is its double-hemmed construction on applicable parts, which eliminates sharp edges and makes the product significantly safer to handle and stock for retail outlet sales. Custom angles other than 90° are available as special order, giving professionals flexibility for non-standard installations without compromising performance.

Key Features & Benefits

Double Hemmed Edges

Double hemming on parts removes exposed sharp edges, reducing the risk of lacerations during handling and installation. This is especially important when stocking flashing for resale at retail or pro dealer outlets where multiple people handle the product.

90° Formed Profile

The standard 90° angle is engineered to match the most common wall-to-roof transition geometry, ensuring consistent fit and fast installation. This reduces on-site fabrication time and the potential for field errors that lead to water intrusion.

Multiple Material Options

Available in Builder-grade, Standard, or 26-gauge Galvanized material, contractors can select the specification that matches their project requirements and budget without sourcing from multiple suppliers. Painted color options further extend compatibility with finished exterior aesthetics.

Standard Color Availability

Painted versions are stocked in Almond (AM), Brown (BR), Black (BK), Charcoal (CB), and White (WH), covering the most common exterior trim and roofing color palettes. Non-stock colors are available as special order for custom project specifications.

Special Order Custom Angles

For installations where the wall-to-roof angle deviates from 90°, Tamlyn can produce the AF7 in custom angles as a special order. This means contractors are not forced to field-bend standard stock, preserving material integrity and ensuring a proper seal.

Leak Prevention at High-Risk Transitions

Apron flashing is one of the most critical components at wall, chimney, and roof intersections — areas that account for a disproportionate share of residential and commercial water damage claims. The AF7 is engineered specifically to manage water runoff and direct it away from vulnerable seams.

Common Applications

Wall-to-Roof Connections

The AF7 is designed specifically for the transition where a vertical wall meets a sloped roof plane, one of the most common points of water entry in residential and light commercial construction.

Chimney Base Flashing

Applied at the upslope side of chimney bases, the AF7 directs water around the chimney and prevents pooling or intrusion at the masonry-to-roof interface.

Dormer Sidewall Flashing

Dormer walls that intersect a main roof plane require reliable apron flashing to seal the vertical-to-horizontal transition and prevent wind-driven rain infiltration.

Skylight Apron Flashing

When used at the lower edge of a skylight rough opening, the AF7 provides a continuous seal that channels water away from the frame and onto the roof surface below.

Addition and Bump-Out Roof Connections

Where a home addition or bump-out roof ties into an existing wall, the AF7 provides a code-compliant flashing solution that integrates with the existing water management system.

Retail and Pro Dealer Stocking

The double-hemmed design makes the AF7 appropriate for retail outlet stocking and counter sales, where product safety for non-trade customers is a consideration.

Frequently Asked Questions

Q: What is the difference between the AF7, AF75, and AF8?
A: The three models differ in leg dimensions. The AF7 has a 3" A-leg and 3-1/2" B-leg; the AF75 is 3-1/2" x 4"; and the AF8 is 3-1/2" x 4-1/2". Select the size based on the required coverage on each side of the transition.

Q: Can I order the AF7 in an angle other than 90°?
A: Yes. Custom angles are available as special order through Tamlyn. Contact Tamlyn directly at 1-800-334-1676 to specify the required angle for your application.

Q: What material should I specify for coastal or high-moisture environments?
A: For high-moisture or coastal applications, specify the 26-gauge Galvanized (26 Ga GZD) option for enhanced corrosion resistance over standard or builder-grade material.

Q: How do I specify a painted color when ordering?
A: When ordering painted versions, append the color code to the item number: AM (Almond), BR (Brown), BK (Black), CB (Charcoal), or WH (White). Colors outside these five are special order.

Q: Is the AF7 suitable for retail counter sales and dealer stocking?
A: Yes. The double-hemmed edge treatment is specifically designed to make the product safer for retail outlet environments where non-trade personnel may handle the product.

Q: Does Tamlyn offer a warranty on the AF7 Apron Flashing?
